HYDRAULIC DERRICK.

SPECIFICATION forming part of Letters Patent No. 248,938, dated November1, 1881.

Application filed August 15, 1881.

To all whom it may concern:

Beit known that I, ORANGE M. Lovnarnen, of Weaverville, countyofTrinity, State ofGalifornia, have invented an Improved HydraulicDerrick, of which the followiugis a full, clear, and exact description.

My invention relates to a novel combination of a horizontal water-wheeland aderrick with certain intermediate gearing, so that the direct forceof a stream of water may be brought to act upon the wheel to drive thehoisting-- drum at a slow or fast speed. The apparatus is controlled bysuitable levers, and from the position of the wheel is entirelyprotected from wet, while the derrick may be turned in any direction.

Referring to the accompanying drawings for a more complete explanationof my invention, Figure 1 is a side elevation of my apparatus. Fig. 2 isa rear view. Fig. 8 is an enlarged View of the driving-wheel, gudgeon,and gear and pinion below platform.

A is the mast, which has a gudgeon, a, at its lower end, turning in astep,B. This step is fixed upon a timber of suitable size and length,and it has a steel button or washer at the bottom, upon which thegudgeon rests or turns when the mast moves. The gudgeon is of steel, andpreferably square where it fits into the foot of the mast. The lowerpart of the gudgeon is turned off round and passes through a hole in thecenter of the water-wheel 0, thus serving as a guide or spindle aroundwhich the wheel turns.

The water-wheel 6 lies horizontally below a platform, D, and its lowerflange rests directly upon the step or casting. The upper flange has aspur-pinion, E, fixed to turn with it. This pinion meshes with anddrives a gear-wheel, F, which is keyed to the lower end of a verticalshaft, G. The upper end of this shaft has a bevel-gear wheel, H, securedto it, and this engages with a similar gear upon the winch-shaft I.

An intermediate shaft, J, is mounted upon the frame, and this shaft hasa sliding pinion, K, upon one end, and a larger gear-wheel, L, upon theother end. The reel-shaft M hasa corresponding gear-wheel and pinionupon it, and when the load to be raised is heavy the (No model.)

pinion K is caused to engage with the gearwheel upon the reel-shaft. Itthe load is light, the larger wheel is thrown into gear with the pinionupon the reel-shaft, while the other is thrown out-of gear. Suitablelevers,0, serve to operate these devices. The bevel-pinion may also bethrown out of gear, if desired, so that the apparatus may be thrown intoor out of gear in two places, if necessary.

The boom P is secured to the mast by plates Q, which are slotted at 0,so as to be adjusted. This is done because the timber will often wind ortwist in seasoning, and thus throw the sheaves out of line. The boom hasa sheave, b, at the top and one, I), in the middle, so that when thework is close to the derrick the middle sheave maybe used, making ashort reach, and when the work is at a distance the upper one may beused. The upper end of the mast has a sleeve or socket, into which theupper gudgeon enters, so as not to be cut when turnlog.

The Water'wheel receives water through a nozzle, R, which is providedwith a gate, S. This gate is operated by a lever extending to a pointwithin convenient reach of the operator.

By this construction I provide a combination of a derrick and apower-wheel which is easily handled, and the wheel is entirely out ofthe way beneath the platform, so as not to throw water to splash theoperator or machinery. v

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In combination with a derrick consisting of the mast A, boom 1?, andthe rope drum or reel and operating-gears, the horizontal waterwheel (Jbeneath the platform, spur-gear and pinions FE, vertical shaft G, andbevel-gears, substantially as and for the purpose herein described.

2. The mastAot'aderrick, having-a gudgeon secured in its footand passingloosely through the hub of the water-wheel G into the supporting-step B,said gudgeon serving to support the mast and as a shaft for thewater-wheel, substantially as herein described.

3. In a derrick having the mast A, boom P,

and tackle, the reel-shaft M, having large and In witness whereof I havehereunto set my small gears upon opposite ends, the intermedihand. ateshaft, J, with corresponding gears and oper- Ming-levers, and thedriving or winch shaft I, ORANGE M. LOVERIDGE. 5 with its gear, incombination with the vertical shaft G, bevel-gears H, spur-gears E F,and Witnesses: the horizontal water-wheel C, substantially as WILLIAM W.YOUNG, herein described.
